I know I have been pretty much a ghost on this site..but lately I have been losing my bettas left and right..has anyone gone through this/ going through this? Its terrible! I find that oen or two of my bettas are sick and then before i can treat them, they pass..its very depressing. Anyway, R.I.P Gatsby, Kai, and Rabbit...you guys will be dearly missed...

Do you share any equipment between them(net or changing cups or anything else) If you have sick fish don't share anything between them.
Can you tell us the symptoms. How about TIKI and Monroe. Do they have any symptoms? Did you share anything between Mako and them?
